Hi Joan - I have been thinking about your question since yesterday, and am glad to see all the suggestions you have gotten. While Zoom is certainly a possibility, it is always more fun to be "in the room" as so much goes on that you miss when only a few are remote.

I have an idea for you - when you approach your friend with an eye towards problem-solving, maybe you could suggest a portable, folding toilet safety rails (fits over commode) or, if sufficient, a removable toilet seat riser. Either should be available for under $40-60 and can be removed and stored when your group is not present. Maybe you could offer to pay for it?

Another option, which we used often when traveling with my Mom, was an old-style folding walker (without wheels.) We would place it backwards over the toilet and it provided a safe way to get up and down.
